Abstract
Results At incision performed 158 ± 112 min after administration, cefpirome concentrations in abscess ranged from below the limit of quantification to 47 mg/L (8.4 ± 14.1 mg/L), and moxifloxacin concentrations ranged from below the limit of quantification to 9.2 mg/L (1.9 ± 3.4 mg/L). Relative to plasma, abscess concentrations of moxifloxacin were significantly higher than of cefpirome (p = 0.037). Inhibitory concentrations of both antibiotics reported for abscess-relevant bacterial species were reached in several, but not in all abscess observations. Antibiotic abscess penetration could not be adequately explained considering covariates such as pH of abscess fluid, or the ratio of surface area to volume of abscesses, linked to plasma pharmacokinetics.
Highlights
Abscesses are often successfully treated with antimicrobial agents when drainage is not feasible, but appropriate data on antibiotic abscess penetration in humans are missing
This study aimed at evaluating and comparing pharmacokinetics of cefpirome and moxifloxacin in the same abscesses to evaluate their eligibility for this indication
After simultaneous administration of 2 g cefpirome and 400 mg moxifloxacin to patients drug levels were measured in plasma over 8 h, and in differently located abscesses (n = 12) at incision
